Mercedes-AMG is developing the second-generation GT with a plug-in hybrid drivetrain producing more than 800bhp – and early prototypes of the petrol-electric super-coupe have been spied testing at the Nürburgring.
Expected to see UK sales in the second half of 2023, the GT 63 E Performance 4Matic will join the recently introduced Mercedes-AMG GT 63 SE Performance 4Matic 4-door and forthcoming SL 63 E Performance 4Matic in a growing range of huge PHEV release models from Mercedes-Benz’s performance car division.
Mercedes-AMG remains tight-lipped on details of the new GT model, although its drivetrain is expected to take heavy inspiration from that of the GT 63 SE Performance 4Matic 4-Door with a front-mounted 4.0-liter twin-turbo V8 petrol engine. and an electric motor located in the rear axle assembly in combination with a 6.1 kWh battery.
It remains to be seen whether the two-door coupe will receive the same 831 hp and 1,082 lb-ft as its five-door hatchback sibling, although the new top-spec GT model looks certain to adopt the 4Matic four-wheel-drive system. + fully variable from AMG, which is not offered on the existing first-generation rear-drive model.
In the GT 63 E Performance 4Matic 4-Door, the electric motor is tuned to deliver a maximum of 201 hp for short full-throttle accelerations, with a smoother 94 hp continuous electric drive available with sufficient battery power reserves . Overall electric range is estimated at 7.5 miles.
The so-called P3 system developed by Mercedes-AMG sees the combustion engine’s reserves channeled through a nine-speed MCT Speedshift automatic gearbox to all four wheels. The electric motor, on the other hand, sends the drive via a two-speed gearbox directly to the rear wheels.
In total, the packaging of the electric motor, battery and power electronics adds 460 kg to the weight of the standard GT 63 S 4Matic 4-Door. Despite the extra weight, it’s supposed to hit 62mph in just 2.9 seconds and have a limited top speed of 190mph.
